AF, GBU could be saved by adding the LD PCM to the Mondo transfer and then replacing the edits in the torture scene and the few other tiny bits to conform to the 161 minute US/International cut. The Italian exclusive scenes would remain Italian mono for the longer cut, with the MGM SE exclusive scene being the grotto which was never shown outside the premiere.

Would LOVE to see such a thing come to fruition. I've only watched the Italian cut, and it currently isn't my favorite movie in the Dollars trilogy. Hopefully, the INL/US cut gives a new perspective...
